Benefits of slim sightlines

The ultra-slim sightlines mean there is less frame and more natural light, allowing you to enjoy the view from your Devon home while enjoying a truly modern appearance.
Despite the slimness of the sightlines, the OW-70 is available in sizes up to 4.8 square metres as either a casement or a fixed window.

Sleek, flush external finish

Whatever the style or age of your property, the OW-70 adds a touch of class and makes it a joy to look at as well as to use.
Prime Windows windows are expertly designed to feature no overlapping external frames. The Slimline Window will add a trim and elegant appearance to your Devon home.
